A comparative study of mini- versus standard laparoscopy in the treatment of renal cysts

This study aimed to investigate the safety and efficacy of mini-laparoscopy for renal cyst unroofing.

Eighty-six patients for treatment of renal cysts that met the selection criteria were included in this study. They were divided into two groups. Forty-five patients underwent cyst unroofing via mini-laparoscopy (Group M), and 43 patients underwent cyst unroofing via standard laparoscopy (Group S). There were no differences between the two groups in terms of sex, age, body mass index or clinical data. Data from the groups were recorded and analyzed.

The average hospital stays were shorter (p = .039) and postoperative painkiller demand was lower (p = .031) in Group M than in Group S. Forty-one out of 45 procedures in Group M were successful, and all 43 cases in Group S were successfully. With a follow-up period of 0.5 to 5.5 years, there was no significant difference in recovery rate (p = .213). Questionnaires showed that patients in Group M were significantly more satisfied with their cosmetic results than were patients in Group S (p = .041).

Our findings suggest that renal cyst decortications with mini-laparoscopic instruments are as safe and effective as procedures using standard laparoscopic instruments. Cosmetically, the results are better with mini-laparoscopy than with standard laparoscopic unroofing.
